Could you please post a picture of the engine in your car. What your mechanic told you isn't correct if you have an '87 300D with an OM603. The 2 replies you received are from VERY knowledgeable members. Please help them help you. You also received excellent advice in the previous thread.

As was previous stated your car will run fine without the EDS functioning. It's only job is to keep the idle at a constant speed. You IP is completely mechanical. The only electricity needed is to start your car. Once it is running no electricity is needed.

My long shot guess is your vacuum pump failed and took out the engine. It should have been louder than some pinging though. Or someone dropped an OM606 into your car before you bought it.

As to your question in the other thread, did my mechanic miss anything. Yes he missed the oil running out of your exhaust. Have you checked the oil level?
